How to log into a 2FA protected YouTube account in Gear VR?

While using Gear VR, I tried to access my YouTube account from both Oculus Browser and Samsung Internet. Since my account is protected by 2-factor authorization, the app tells me to click the "yes" button that should appear on my registered phone. However, when the Oculus app is running, this notification is not displayed. I tried to remove my phone from the gear, but no notification neither. What is the easiest way to log into my 2FA-protected YouTube account from Gear VR?
